Description

Electrically heated curler

[technical field]

The utility model relates to the pin curl perm transmitting apparatus, especially relates to a kind of electrically heated curler that the curly hair core of hollow is arranged on the hair-waving utensil that is used in.

[background technology]

Traditional electrically heated curler utilizes the heater element of common PTC heating resistor as curler.Because PTC heating resistor size is less, coincide with the inwall of curler is difficult, directly heat conduction is had any problem, and will adopt 2 blocks of semicircular opening elastic metallic pipes to conduct heat between the inwall of PTC heating resistor and curler.So traditional electrically heated curler has following shortcoming:

1. weight is heavier, for the client of hair-waving, will bear the weight of tens electric heating volumes when hair-waving is arranged on the head, and it all is very big burden to the client that each curler slightly increases some weight.

2. thermal inertia is big, and it is slow to heat up, and the time that the client of hair-waving waits is long.

3. the temperature of curler can not control to adjust on request.

[summary of the invention]

The technical problems to be solved in the utility model provides that a kind of weight is lighter, and thermal inertia is less, and electrically heated curler faster heats up.

The technical problem that the utility model further will solve provides the electrically heated curler that a kind of temperature can control to adjust.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of electrically heated curler, the curly hair core and the heating that is arranged in described hollow curly hair core that comprise hollow, described heating is the metal heating film, described metal heating film is rolled into cylindric, invests the inwall of curly hair core.

Above-described electrically heated curler, described metal heating film cylindraceous preferably circumferentially overlap in the end of heating film along cylinder.

Above-described electrically heated curler, described metal heating film cylindraceous preferably respectively have the breach of at least 1 correspondence in described 2 ends, described overlap forms cross structure.

Above-described electrically heated curler preferably also comprises 1 temperature detect switch (TDS) in the curly hair core of hollow, described temperature detect switch (TDS) is serially connected in the lead of metal heating film with the power supply connection.

Above-described electrically heated curler preferably also comprises 1 temperature sensor in the curly hair core of hollow, described temperature sensor connects by the attemperating unit of lead with power supply.

Above-described electrically heated curler is characterized in that, described temperature sensor preferably is affixed on the metal heating film.

Above-described electrically heated curler, described temperature sensor can be negative tempperature coefficient thermistors.

Above-described electrically heated curler, the best end sealing of described curly hair core, the other end also comprises 1 end cover, has metal contact to form the socket that connects power supply on the described end cap, and the lead that the metal heating film connects power supply is electrically connected with the metal contact on the curly hair core end cap.

The utility model has been compared following advantage with prior art:

1. the used heating of the utility model is the metal heating film, described metal heating film is rolled into cylindric, invest the inwall of curly hair core, there is not big space between the inwall of metal heating film with the curly hair core, help the heat conduction of heating, do not need metal tube to come heat conduction between the two with the curly hair core.Metal heating film itself is very light simultaneously, so the utility model is more light than traditional electric heating curly hair core.

2. the characteristics of metal heating film are that thermal inertia is little, so the utility model quick heating, the time that client waits for during hair-waving can shorten.

3. the metal heating film is planar exothermic material, can form thermal conductive surface to greatest extent with the inwall of heated curly hair core.This mode of heating heat conductivity is good, and the Electric radiant Heating Film self-temperature is very not high, does not have rubescent, scorching hot phenomenon to produce, and the radiation heat loss is very little.So the utility model thermal efficiency height is compared with prior art and can be saved the energy.

4. temperature is controlled good.The metal film element can satisfy the accurately requirement of control, and temperature control precision can reach ± and 2%.The utility model such as further employing temperature detect switch (TDS) or temperature control circuit just can accurately be controlled the operating temperature of electric heating curly hair core.

[specific embodiment]

In the utility model electrically heated curler embodiment shown in Figure 1, comprise the curly hair core 1 and the heating metal heating film 3 that is arranged in hollow curly hair core 1 of hollow, endoporus one end of curly hair core 1 seals, and the other end is by end cap 2 sealings.Metal electric heating membrane is the flake structure of three layers of combination, the polyimide insulative film that upper and lower top layer is good by temperature tolerance, insulating properties are good, and middle resistance circuit pressing of making for the specific alloy paper tinsel forms the border seal of insulation film.Metal heating film 3 is rolled into cylindric, invests the inwall of curly hair core 1.

As shown in Figure 2, the both side ends of metal heating film respectively has the breach 3a of 1 correspondence, and the metal heating film is rolled into when cylindric along cylinder circumferentially at the end of heating film overlap joint, and shown in Fig. 3 (a), overlap forms cross structure.Be another overlapping mode shown in Fig. 3 (b), metal heating film both side ends respectively has the breach 3a of 2 correspondences, and overlap also forms cross structure.The both side ends leaving certain gaps uncovered by the economic plan of metal heating film, the benefit that overlap forms cross structure is that metal heating film cylindraceous has certain outside tension force in curly hair in-core hole, can not crispatura, can fit with the curly hair core well and conduct heat, to reduce the resistance of outside heat transfer.

Have 3 metal contact 7 to form the socket that electrically heated curler connects power supply on the end cap 2 of present embodiment, the lead that the metal heating film connects power supply connects with the metal contact 7 on the curly hair core end cap.In the present embodiment, also comprise 1 temperature detect switch (TDS) 6 in the curly hair core 1, temperature detect switch (TDS) 6 is serially connected in the lead of metal heating film with the power supply connection, to place restrictions on the maximum operating temperature of electrically heated curler.Also comprise 1 negative tempperature coefficient thermistor 5 in the present embodiment as temperature sensor, thermistor 5 is affixed on the metal heating film 3, temperature in order to perception metal heating film, be connected with the attemperating unit of metal contact 7 by lead, make the operating temperature of electrically heated curler can obtain regulation and control with the electrically heated curler power supply.The circuit theory of present embodiment as shown in Figure 4.
